Is it a true V24, or two V12s siamesed together? In other words, does it have one 12-cylinders-long crankshaft, or two shorter crankshafts bolted together? I know GM had a V20 locomotive engine at one time, but I cannot imagine how a single crankshaft this big wouldn't have massive torsional flex. And imagine line-boring the block for it!

If it came out of a boat, I wonder how he will cool it without having an ocean of water nearby.

I agree, it looks like more show than go. It does make a nice noise though.John

Glad you guys liked it.... or at least liked critiquing it! I think it's fun fodder for discussion. I haven't a clue if it can do what he says. Not my line of expertise. (my Detroit is the first "diesel" I ever even touched!) BUT, that motor has some kind of "Cool Factor"!!!!!!!!!!!!! :oI'd like to find out more about it to see if in fact the guy was blowing as much smoke as the engine was blowing exhaust. I didn't really care about that much at first, but all the skepticism has me wondering. Either way, this motorhead thinks it's the Kats!!!!! It would still look good in my bus!!!

I remember Big Mike 1 was around 2800 hp I don't doubt the HP you can get a 1000 hp from a 8v92 with 2 turbos, the air box on top of that engine had to cost a small fortune looks to me like he used some of the series 149 designs, I would have went with the V20 149 engine lot less work and money to get the same hp

The 24V-71 was a marine engine that is two 12 cylinders bolted together. Originally had four blowers and 4 turbochargers and put out 1800hp @2300rpm. This one is a show engine. Personally-I think all those blowers are empty with just shafts in them for show. I don't think there would be anyway a single belt from the crankshaft could power all those blowers at the same time. If you look carefully, the rear three blowers have a powering belt both on the front and the back of the blower-with them calling that two blowers. I think the original 4 blowers are still under the air box actually powering the engine. Also notice how "loose" the belts are when the engine is running. If you've ever seen a dragster with a blower, the belt tightens up real fast. And especially with "12 blowers", those belts would be really tight. But-you've got to admit-it is a really magnificent looking engine! Good Luck, TomC

It's mostly show....... Go Google 24V71 and find the build pics of the 8 supercharger setup, all total BS !! . It's a 24V71 NA . a 12v71NA was rated at 475 HP @ 2100 ........Chome it if it don't go!! If you listen to that dyno run it never made a hard pull ...ALL B.S.!!!!

I don't think they ever made a 24v71 NA the last one I was close too was a 2400HP at 2500 rpm 2 monster turbos DDEC engine in a ferry fwiw that engine and ferry is running everyday across the Houston Ship Channel

google 24V71 powered peterbilt 359 , theres a complete photo build of a 24V71 T & that 24V71NA W the 8 BDS blower Showpiece bolted to a 24V71NA that they took 4 turbos off ...It might make a 1000 HP on good day at sealevel .
